So far in 2012, WR Greg Jennings has experienced a concussion that kept him out of two preseason games, a groin injury that sidelined him for Week 2 against Chicago, and now a re-aggravation of that groin injury that could keep him out even longer.

He described himself as “extremely frustrated” at everything he’s having to deal with this season, which is the final year of his current contract. After missing the Bears game, Jennings played in Week 3 in Seattle and experienced some pain, which he felt was normal.

Then early last Sunday against the Saints, he said he “tweaked” it and it gradually got worse to the point he was telling his teammates he knew he wouldn’t be able to finish the game. He did catch his first TD pass of the season against New Orleans.

“Seven years playing this game at this level, I’ve never experienced what I’ve experienced this year,” said Jennings, emphasizing that he’s not worried about his contract situation. “It’s new territory for me, but I’m getting through it.

“You feel like everything’s OK, but the moment you go to do something you’re accustomed to doing it’s just not there. Only time will allow that to come back. I have to take the time.”

How much time is unknown at this point. He said the plan will be to ease him back into things once he feels healthy again, saying only of the timetable, “however long it takes.”

“Now it’s just a matter of being smart,” Jennings said. “I can’t keep having that up-and-down, in-one-game-out-the-next. I can’t keep doing that to myself or the team.”
